Thanks - that's a great reply, and makes a depressing amount of sense. In the case of page layout issues rather than click fraud, though, I still can't see why

Thanks - that's a great reply, and makes a depressing amount of sense. In the case of page layout issues rather than click fraud, though, I still can't see why it doesn't make more sense to work with the publisher to achieve a layout everyone's happy with. I'm not sure what the bad guys could get out of knowing that Google doesn't like inline ads without a border, for example.
